Sea serpent coil + undeath is plague now ,this buffs have no counter combine this with mara and bloodspawn with giant spell weapon or spell damage and we have unkillable killing machine, you can't defeat something like that. Yes i know i'm complaining about game mechanic but this kind of combos are too strong and have 0 counters.
People will come ant tell just use it too ,ok i can but if someone don't want? This thing is totally counter to play as you want definition and i want to have tons of armor penetration and do damage this way but mitigation like that is impossible to counter.
Only healthy buffs are armor + minor ,major protection and they should be.
Those unique buffs should be high armor stats maybe Sea serpent +10000/15000 armor if full hp , person are strong at full hp but berserk like when have lower ,combined with extra armor from vampire( work like Pariah) they have identical but this way it's penetrable with nice armor penetration.
Current thing is just disgusting.
